Remote and hybrid work has fundamentally changed how businesses think about productivity and security monitoring. When employees are working from home networks on company devices — or sometimes personal devices — visibility into computer activity becomes both a business risk management question and a compliance requirement.
SentryPC is one of the more complete solutions in this space, combining content filtering, time management, and detailed activity logging in a cloud-accessible dashboard. We tested it extensively across both employer and parental use cases in 2025.
What SentryPC Does
SentryPC is an agent-based monitoring platform for Windows and Mac computers. Once installed (silently or visibly, your choice), it:
- Records application usage with timestamps
- Captures periodic screenshots
- Logs keystrokes (with configurable sensitivity)
- Tracks websites visited with time-on-site
- Blocks or limits websites and applications by category or specific URL/app name
- Enforces time limits and schedules (e.g., no social media during work hours)
- Sends alerts for specific keywords or policy violations
- Syncs everything to a cloud dashboard accessible from any browser
The cloud architecture is the key differentiator from legacy monitoring tools. You don’t need to be on the same network — you can check in from your phone while traveling and see exactly what’s happening on a monitored device in real time.
Setup
Installation takes about 5 minutes per device. You download the agent from your SentryPC dashboard, run it on the target computer, and it immediately starts syncing data. The agent can run silently (hidden from the user) or with a visible notification, depending on your use case and jurisdiction.
For business deployments, you can push the installer via Group Policy or any remote deployment tool. There’s no per-device setup beyond running the installer — all configuration is done in the dashboard and applies to all devices assigned to an account.
The Dashboard
SentryPC’s web dashboard is clean and functional. The main view shows a summary of each monitored device — online status, last active time, and recent activity snapshot.
Drilling into a device gives you:
Activity logs — timestamped records of every application opened, website visited, and search performed. Filterable by date range, making it easy to pull a specific window of activity.
Screenshots — configurable to capture every 1–60 minutes, or on trigger events. Images are stored in the cloud and accessible from the dashboard. This is useful for compliance purposes and for understanding context around activity logs.
Keylogger — logs all keystrokes by application. You can set this to only capture in specific apps (e.g., only browser input) to reduce noise. In a business context this is typically used for HR investigations rather than routine monitoring.
Content filtering — block by category (adult content, gambling, social media, gaming) or by specific URL/app. Blocks take effect immediately without requiring a device reboot.
Alerts — set keyword triggers that generate email notifications. Useful for detecting policy violations, data exfiltration attempts, or concerning personal activity.
Employer Use Case
For businesses, SentryPC solves several overlapping problems:
Productivity monitoring: Understanding how employees spend time on company devices, especially for remote workers. Activity logs and time tracking give managers data to address productivity concerns with evidence rather than assumption.
Policy enforcement: Blocking sites and applications that violate acceptable use policies. This includes recreational browsing during work hours, file sharing services, personal cloud storage, and social media — depending on your policy.
Security investigations: When an incident occurs, having months of activity logs, screenshots, and keystroke data makes forensic investigation significantly faster.
BYOD environments: SentryPC can be deployed on personally-owned devices with employee consent, which is increasingly required by cyber insurance policies for remote workers accessing company systems.
Important: Before deploying monitoring software, consult your employment counsel. Requirements for employee notification vary by state and country. Most jurisdictions allow silent monitoring on company-owned devices with appropriate policy disclosure; some require explicit notice regardless of device ownership.
Parental Use Case
For parents, SentryPC provides a level of oversight beyond what built-in parental controls offer. The combination of content filtering, time limits, and keystroke capture makes it useful for:
- Blocking adult content and age-inappropriate platforms
- Setting homework hours (no gaming or social media 3–8pm)
- Monitoring for cyberbullying via keyword alerts
- Understanding who children are communicating with
The cloud dashboard means you can check activity from your phone without being home, which many parents find more practical than on-device parental control apps.
Pricing
SentryPC uses a flat monthly or annual subscription model per account (not per device). Plans include:
- Basic (~$69.95/year): 1 computer
- Premium (~$99.95/year): 3 computers
- Business (~$149.95/year): unlimited computers in an account
The unlimited business tier is exceptional value for organizations monitoring more than 3 devices. At $150/year for unlimited endpoints, the per-device cost drops to essentially nothing at scale.

Pros and Cons
Pros:
- Excellent cloud dashboard — accessible from anywhere
- Genuinely unlimited devices on the business plan
- Strong content filtering with category and custom rules
- Screenshots provide context that logs alone can’t
- Low per-device cost at scale
Cons:
- Mac support has fewer features than Windows
- Screenshot storage can accumulate quickly on high-frequency settings
- Mobile device monitoring is not supported (Windows/Mac only)
- Interface feels dated compared to newer competitors
How It Compares
| Feature | SentryPC | Hubstaff | Teramind |
|---|---|---|---|
| Keystroke logging | ✅ | ❌ | ✅ |
| Screenshots | ✅ | ✅ | ✅ |
| Content filtering | ✅ | ❌ | ✅ |
| Unlimited devices | ✅ (business plan) | ❌ (per seat) | ❌ |
| Price (10 devices/yr) | ~$150 | ~$600 | ~$1,200 |
For price-sensitive SMBs, SentryPC’s unlimited business plan is hard to beat.
Verdict
SentryPC is a well-executed monitoring platform that covers the core use cases for both employers and parents without requiring enterprise pricing or IT complexity. The cloud dashboard works reliably, the content filtering is genuinely effective, and the per-device cost at scale is lower than any comparable product we’ve tested.
If you’re looking for basic time tracking only, simpler tools exist. If you need deep DLP or UEBA capabilities, look at Teramind. But for most SMBs and families who need a capable all-in-one monitoring solution, SentryPC delivers strong value.
